Lying and Psychology
Lying is a very complex behavior, occurring in different forms and situations. It requires the liar not only to constantly keep the perspective of the to-be-deceived person in mind, but at the same time to remember and activate the truth, prevent the truth from slipping out, and flexibly switch between the lie and the truth. The affective correlates of lying seem to range from guilt and the fear of being discovered to a delight after successfully getting away with a lie. Because of the observed variability in the affective correlates of lying, most recent research on lie detection has started to explore methods that are based on cognitive rather than affective processes. Those methods aim either to measure the increased cognitive load during lying, or to measure lying indirectly by assessing whether a suspect recognizes critical crime-related information.
